Yeah. I'm doing most of my work horizontally right now deliberately. I can build vertical adders watching tutorials, but I don't always understand why certain redstone setups are functioning as specific gates. (Also, I find it harder to stack vertically without using WE) The creator of the tutorial seems to confirm that I'm thinking correctly about signed binary to BCD conversion. His converter doesn't seem much simpler than what I'd already thought of, though. It looks like he's essentially using XOR logic to conditionally invert and then CIN to half adders. The only thing that makes his design better than my current plan is the insta-carry instead of ripple carry. If there really isn't a shortcut way to do this, I'm cool with building my original design. I'll probably look a little more into insta-carry though since I want it to be at least reasonably fast.
